Terapia fotodinâmica em dermatologia: princípios básicos e aplicações

Abstract: Resumo:A terapia fotodinâmica envolve a administração de uma droga fotossensibilizante e sua ativação subsequente pela luz de comprimento de onda correspondente ao espectro de absorção do fotossensibilizador. Atualmente, a terapia fotodinâmica tópica é aprovada para o tratamento de condições oncológicas cutâneas como queratoses actínicas, doença de Bowen e carcinoma basocelular superficial em diversos países do mundo. Estudos multicêntricos controlados e randomizados demonstram a alta eficácia e resultado cosm… Show more

“…Study shows Aggregatibacter actinomycetemcomitans (A. actinomycetemcomitans) have protoporphyrin IX with 405nm soret band spectrum and peak Q band at 510 nm, 545 nm, 580 nm, 630 nm, 670 nm, and 700 nm. 4,5 Antimicrobial effect is a phototoxic response due to singlet oxygen which caused oxidative damage to cell DNA and changes in molecular mass of some cell membrane proteins and plasma membrane. 2,7,6 Oxidative damage in bacterial cells generally occurs in the DNA cells and other cell organelles, but damage to the cell organelles can differ, depended on types of bacteria and photosensitizer used.…”
